|
Batesian mimicry is when a harmless species resembles a dangerous species. A Mullerian mimicry is when two poisonous species look alike.

|
What is the difference between the k-selected species and the r-selected species?
|
The k-selected species produce few offspring, invest heavily in parental care, and thus have offspring with a good chance of surviving to reproductive age. R-selected species has a large number of offspring and provides little parental investment, with the result that only a few offspring survive to reproduce.
